SPECIFICATION forming part of Letters Patent No. 561,187, dated June 2,1896.

Application filed August 14, 1895.

To a/ZZ whom t may concern:

vBe it known that I, WILLIAM H. WILKIN- SON, a citizen of the UnitedStates, residing at Boston, in the county of Suffolk and State ofMassachusetts, have invented certain new and useful Improvements inOil-Oups;and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to. which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to figures of referencemarked thereon, which form a part of this specification.

This invention relates to oil-cups, particularly to that class in whichthe supply-valve is operated by means of a rocking lever.

The object of my invention is to provide for the locking of the coverwhich closes the filling-aperture, and my improvements are embodied inthe arrangement of the parts whereby a positive locking of theiilling-hole cover is secured whenever the supply-valve is open;furthermore, in the relation of the parts whereby the spring whichoperates the supply-valve is given an additional function, or the dutyof holding the cover closed.

The drawings represent, in Figure 1, a sectional elevationlongitudinally of an oil-cup embodying my invention. Fig. 2 is a sideelevation in part with the lever down and the supply cut off. Fig. Sis aplan.

In the present instance my invention is applied to a sight-feedoil-cup,which comprises a metallic flanged cup or base 2, provided witha central hollow tube 3, screw-threaded at both ends, the lower portionprojecting below the base and adapted to engage a pendent apertured post4, containing a removable glass duct 5, through which the oil passes.The eX- tremity of said post is screw-threaded for attachment of the cupto the bearing or other point to be oil-supplied. The metallic top pieceG consists of a hanged cover formed with a pendent hollow sleeve 7,which engages the tube by screw-thread attachment, and this confines aglass cylinder 8, which forms the oil-cup chamber, the ends beinginclosed and clasped by the flanges 9 9. In this way an oilreservoir isreadily constructed and the glass, if broken, can easily Serial No.559,299. (No model.)

be replaced. Gaskets lO IO at the base of the glass portions createtight joints and prevent the escape of oil.

In connection with this oil-cup is a valve 12, secured to a spindle 13,spring-actuated at let, the latter serving to normally hold the valveupon its seat. This spindle is adapted to turn axially in the cap aslikewise to move longitudinally and projects through the cap, beingslotted at 19. This slot is arranged to receive a bolt or pin 2l, whichmoves freely in the slot and serves to secure the operating valve-leverI5. This latter element consists of a flat plate or thumb-piece withabifurcated portion 16, adapted to straddle the spindle.

' The device to regulate the feed consists in a screw 17, adapted tomove longitudinally in and out of the spindle-top, and said screw ispositively locked when the valve-lever is upright, the walls of the legsI6 clasping the head of the screw and thus preventing said screw fromshifting its position and so changing the feed.

In connection with this oil-cup is a pivotal cover 18 in the shape of afiat plate 19 arranged to rest upon the cover 6 and serves to close thefilling-orifice and prevent foreign substances from entering. The centerof motion of this cover is the axis of the. spindle. Above the cover 18and resting thereupon is an annular block 2O loosely aboutthe`valvespindle and held in this position thereby. The upper face ofthis block serves as a fulcrum for the valve-lever.

From the arrangement of the above described elements it will be seenthat the valve is held firmly to its seat by the spring 14 when thelever is down. At this time the oil-discharge is closed, while the coverand the fulcrum-block are loose and free to revolve. The cover can nowbe readily moved from over the supply-opening and the lubricating fluidentered. The cover is now returned to place and the lever thrown into anupright position. This act serves to bring the bolt 2l against 'theregulating-screw, while the lower end of the lever acting upon the block2O as a fixed point now lifts the valve-spindle, and the IOO tension ofthe spring is at once transferred to the fulcrum-block and iilling-holecover IS. The latter, it is evident, is now held firmly in one positionby the valve-spring and with the same pressure which heretofore wasexerted upon the valve,thus preventin g movement by vibration or jar ofthe machine. However, it may be moved manually should occasion require.This pressure is sufiicient to retain the cover securely locked andclosed at such times as the oil-cup is discharging oil; but when thelever is thrown down and the feed stopped then the cover-plate isrelieved from the pressure of the valve-spring, but it is in readinessat all times to be moved manually for the introduction of oil or otherlubricant into the oil-cup.

Thus the advantage of my improvements consists in locking the fillinghole cover against jar or vibrations of the machine when the oil-cup isin active service and releasing,r the said cover when. the oil supply isshut oif, and furthermore in transferring the valvespring pressure fromthe valve, when open, to the oilcup1il1ing cover, and conversely.

Afurther advantage in the employment of Y the valve-spring to secure theoil-eup-illinghole cover consists in the fact that the spring alwaysexerts a positive active function as long as the cup lasts, whilecheck-nuts or other fastening devices soon wear, become loose byconstant jar and vibration, and fail to perform their duty.

lVhat I claim is-n l. In an oil-distributing device, the combi nationwith a valve, and a filling-hole cover for the admission of iluid andadapted at times to move freely upon the spindle and swing thereabout,of aspring to hold the valve closed, and means by which the tension ofthe spring is transferred to the cover to prevent free movement when thevalve is open, substantially as stated.

2. In an oil-cup, the combination with a valve,a valve-spindlc,and anactuating valvelever adapted for free rotation with the spindle in theoil-cup, of a valve-spring, a loosely mounted filling-hole cover, and afulcrunr block, whereby the spring-pressure is alternately transferredfrom the valve to the filling-hole cover and vice versa, upon openingand closing of the valve, substantially as specified.

3. [11 combinatian witlfan oil-cup, an axially-movable valve, aspring-actuated valvespindle having a slotted end proj ecting above saidcup, and an adjusting-screw, a swing# ing filling-hole cover, afulcrunrblock loosely fitted about the valve-spindle, and a valveleveradapted to transfer the pressure of the valve-spring to the filling-holecover in the act of opening the valve, substantially as set forth.

In testimony whereof I alix my signature in presence of two witnesses.
